A WebAssembly Milestone: Experimental Support in Multiple Browsers
WebAssembly is an emerging standard whose goal is to define a safe, portable, size- and load-time efficient binary compiler target which offers near-native performance—a virtual CPU for the Web. WebAssembly is being developed in a W3C Community Group (CG) whose members include Mozilla, Microsoft, Google and Apple. I’m excited to announce that WebAssembly has reached […]

asm.js is an easy-to-optimize subset of JavaScript. It runs in all browsers without plugins, and is a good target for porting C/C++ codebases such as game engines – which have in fact been the biggest adopters of this approach, for example Unity 3D and Unreal Engine. Obviously, developers porting games using asm.js would like them […]

Synchronous Execution and Filesystem Access in Emscripten
Emscripten helps port C and C++ code to run on the Web. When doing such porting, we have to work around limitations of the web platform, one of which is that code must be asynchronous: you can’t have long-running code on the Web, it must be split up into events, because other important things – […]

Massive: The asm.js Benchmark
asm.js is a subset of JavaScript that is very easy to optimize. Most often it is generated by a compiler, such as Emscripten, from C or C++ code. The result can run at very high speeds, close to that of the same code compiled natively. For that reason, Emscripten and asm.js are useful for things […]

Resources for HTML5 game developers
Today we released Firefox 31 and it offers a couple of new features that help HTML5 game developers to code and debug sophisticated games. In addition Mozilla blogged about the first commercial games leveraging asm.js, Dungeon Defenders Eternity and Cloud Raiders both of which were cross-compiled in to JavaScript using the Emscripten compiler. Games like […]
